Sarcee was part of the plans for a ring road going back to the '50s:

By the '70s the alignment on the east and south sides—between 68th and 84th St East, and along 22X—was already settled. Starting from the intersection of 22X and 37th St SW the west side was planned to go north along the 37th St right of way, blow through the Weaselhead and connect to Sarcee Trail, follow Sarcee Trail's current alignment up to 16th Ave NW, blow through Bowness and Silver Springs to link up with Sarcee Trail NW, and follow the current Sarcee Trail NW alignment just past John Laurie, whereupon it would have continued northeast through was is now Edgemont, The Hamptons and Hidden Valley and link up with the current Stoney Trail NW at Beddington Trail.
